Boys’ night out at HBO

Ellin's next comedy series set on Wall Street

Doug Ellin has sold HBO his next comedy series, which explores the question, “What if the guys on ‘Entourage’ grew up?”

“Entourage” creator-exec producer Ellin is writing an untitled half-hour he described to Daily Variety as a “mature version of ‘Entourage’ set on Wall Street.” The action revolves around a fortysomething hedge fund trader and his circle of guy pals.

Project is the first to emerge from Ellin’s overall development deal with HBO, which renewed “Entourage” for a fourth season last month.

Ellin will exec produce the pilot with Stephen Levinson. Idea was hatched by the pair after they realized several of their friends from college — “regular, fraternity brother-type guys,” Ellin said — were banking $40 million-$50 million a year on Wall Street.

“They make Vince look like a peasant,” Ellin joked.

“I wanted to do a show that deals with these men who are making obscene amounts of money at a young age,” he said. “It’s a comedy, but it will be more mature than ‘Entourage.’ The characters will be dealing with grown-up issues such as marriage, getting older and working within the professional ranks.”

A script is in the works and Ellin cites several real-life situations as the basis for the pilot.

“New money — the kind you don’t inherit — puts you on a different stratosphere, and that’s what I think will be interesting in this show,” Ellin said, adding the group of friends will comprise both wealthy and middle-class guys. “What happens when you’ve made all of this money? What kind of stress does it put on your relationships?”

Endeavor-repped Ellin just wrapped the second half of the third season of “Entourage,” which will bow next year.
